PATENT VENTILATOR.

Application filed April 5, 1922. Serial No. 549,678.

To all whom. t may co'iwern.'

Be it known that I, FREDERICK 0. REICH- ARDT, a citizen-of the UnitedStates, residing` at Marietta, in the county of lashington and State ofOhio, have invented certain new and useful Improvements in Ventilators,of which the followingr is a specification, j i y This invention relatesto improvements in ventilators for windows and has as one oi"` lvide.'tor the even and correspondinpY adjustment oi the movable sections ofthe ventilator through the manipulation of a single operatingr means sothat after the ventilator has been disposed within the window openingrit may be readily expanded to the required width to till the opening.

nother object of the invention is to prfovide a novel constructionwhereby the ventilator may he made substantially in its entirety fromsheet metal and simple and inexpensive fittings.

A Jfurther object of the invention is to provide a novel arrangementof,A slats and a novel means whereby the vslats may be adjusted tocontrol the passage of air through the ventilator screen, and securelyretained in positions or adjustment.

Figure 7 is a detail horizontal sectional view on the line 7 7 ofFigure2; and

Figure 8 is a view similar to Figure 4 illustrating a modifiedarrangement of the slats and the adjusting' means therefor.

Generally speaking the ventilator 'embodyinelr the invention comprisesan intermediate or main section which is 'indicated in general by thenumeral l, and end sections indicated in general by the numeral 2, meansbeing provided for adjusting the end sections with relation to theintermediate section so as to expand or contract the ventilator as awhole and thus adapt the same for disposal within window frames ofvarious widths. I

The intermediate or main section l of the ventilator comprises atrame-like structure including an upper rail. a lower rail` and endStiles indicated in general respectively by the numerals 4 and 5.rlfhese several parts are formed from sheet metal. The, upper rail 3comprises a vertically disposed portion` (i, a horizontallydisposedportion 'i' which extends inwardly or rearwardly at right anglesfrom the plane ot the portion ti,

a portion 8 which entends longitudinally of .the edge oi the portion 7and upwardly at right angles with relation to the plane thereof, and aflange y9 which projects inwardly or rearwardly at right angles from theplane of the portion 8 and entends alone the upper edge thereof and hasits tree edge portion turned vdownwardlyand -forwardly as at l0. Theportion 8 is designed, in the use of the ventilator. to seat against theinner side oi3 the bottom rail of the window sash when the. sash islowered' to position resting upon the portion 7 oi2 the rail 3 thusinsuring ot a closingT of any space that might otherwise exist betweenthe sash and the top of the ventilator, The numeral ll indicates anapron portion which depends from the lower edge of the verticallydisposed portion 6 and is inclined in the manner' shown in Figures 3 and4 oi: the drawings' and provided between its ends with a recessindicated by the numeral l2,

The upper rail 3 of the frame structure of the intermediate sectionJturther includes a face pla-te 13 which is secured in any suitablemanner as for example byvrivets 14 to 1 flange 2L the portion 19 beinglikewise pro the rear face of the portion 8 of the previously' describedsection vof the top rail, and

The bottom rail 4 comprises a rail scc-v tion 13 having a verticallydisposed portion 19 and an upwardly andrearwardly inclined portion 20provided `along1 its upward edge with an upwardly and forwardly inclinedvided along its lower edge witha fiange 22 adapted to rest tia-t uponthe sill of the window frame within which the ventilator is arranged.The said bottom rail further includes a rail section indicated by the,uu

meral 23 and in the nature of a face plate which is disposed parallel tothe pla-te 13. and in a plane therewith and provided along its` loweredge with an inwardly projecting vwith a longitudinal tiange 24presented edgewise to the flange 22. vThe upper edge portion of theplate 23y is bent upon vitself to provide a flange 25 securing the loweredge of the foraminous screen 17.

Bracket members 2G are `secured to the inner or rear face of the member6 of the top rail and extend across the space between said member andthe face plate 13 andare likewise secured to the said plate so that theplate is braced at its intermediate portion1 with relation to the saidmember 6. ln a like manner brackets 2T are provided upon the memberorsection 18 of the lower rail 4 and are. secured thereto and to theface plate 23 to relatively brace these parts. The wire screen fabric 17will of course be more or less tautly stretched between the upper andlower rails of the frame structure. v

Each of the stiles 5 comprises an intermediate or web portion indicatedby the numeral 28 and provided at its vertical edges with danges 29occupying parallel planes at right angles to the plane of the web 28.The stiles 5 are disposed at their upper and lower ends respectivelybetween the member 6 and face plate 13 of the upper rail and the member13 and face plate 23 of the lower rail and their flanges 29 are. securedto these parts by riveting or otherwise. The web 28 of eac-h stile 5 ispreferably formed bend 30 extending throughout its entire height- -andproviding a portion 31offset with relation to the other portion of thesaid web.

The. structure above described completes the main or intermediatesection of the ventilator except for the slats which are mounted withinthe frame structure and operated by a means and in a manner to bepresently set forth.

Each of the end sections 2 of the ventilator comprises spaced front andback plates indicated respectively by the numerals 32 and 33. one of theplates as for example the front plate 32 having its upper end portionbent over at right angles as at 34 and secured to the adjacent side. ofthe plate 33. The numeral 35 indicates a bracing member which isdisposed and secured between the laterally outer edge portions of theplates 32 and 33, this bracing member preferably comprisintcr anintermediate portion or web 36 and side flanges 37 which latter areriveted.. welded. or in any other manner-secured to the said edgeportions of the plates 32 and 33. The plates 32 and 33 are so spacedwith relation to each other that the end sections 2 are adapted, as awhole. to slidably fit over the ends of the frame structure of theintermediate or main section 1. In this manner the end sections 2 areadapted to be slidably adjusted upon and with relation to the ends ofthe main or intermediate section 1 and when properly adjusted aredesigned to seat at their outer vertical sides against the stiles of thewindow frame within which the ventilator is disposed. ln order toprevent displacement of the end sections with relation to theintermediate section. it is preferable that the upper end of the plate33 be extended above the portion of the plate 32 and provided with aright angularly bent tongue 33' designed to slidably engage beneath theportion 9 of the top rail section 6 and behind the flange 10 thereof.The means provided for ad'usting the sections 2 includes tubular slideswhich are arranged in axial alignment with each other and threaded orotherwise secured at their relatively remote ends in sockets or bosses39 upon bracket. plates 40 in turn secured to the inner sides of theintermediate portions 36 of the respective bracing members The tubularslides 3S fit freely through openings 41 formed in the upper endportions of the st-iles 5 and are provided at. their relatively adjacent,ends with ferrules 42 interiorly threaded for the reception of theoppositely threaded ends of an adjusting screw rod 43. the threads ofthis rod being right and left hand and the rod being provided midwaybetween its ends with a knurled finger wheel 44 by which it may beconveniently rotated. The bracket members 26 are provided with slots orrecesses 45 in which the tubular slides 38 are rotatably and slidablyreceived, the slides being in this manner guided and braced duringadjustment. By reference to Figure 4 it will be evident that a portionof the periphery of the finger Wheel 44 projects through the recess 15in the face plate h13 to such an extent as to render the wheel readilyaccessible for the purpose of rotating the same to correspondinglyvrotate the adjusting screw rod 43 and thus draw the tubular slides 38toward each other or move them .apart and correspondingly adjust the endsections 2 with which these sildes are associated.

In that form of the invention illustrated particularly in Figure 4, theslats are indicated in general by the numeral 46 and are preferablyformed of sheet metal, and each slat comprises a fiat body portion 47havinga flange 48 extending along its upper edge and a flange 49extending alongits lower edge. The flanges 48 and 49 lie approximatelyat right angles to the plane of the body portion 47 of the slat andextend in opposite directions from said plane and in the assembledrelation of the slats, and when the slats are closed as sho'wn in thesaid Figure 4` the upper flange 48 of one slat will overlap or overliethe lower flange 49 of the slat next above it. They slats are providedat the ends of their body portions 47 with flanges 50 which project inthe same general directionas the flanges 48 and which are pivotallyconnected at their upper ends as at 51 to the offset portions 31 of therespective stiles 5. Bars 52 are arranged at the ends Vof the slats 46and arevpivotally connected as at 53 to the lower ends of the. flanges50. It will now be evident that an upward and forward swinging movementof any one of ,the slats 46 as for example the uppermost slat, willresult in a corresponding movement of the other slats because of theirmutual connection through the medium of the bars 52. Therefore, as ameans for adjusting the slats, a link member 54 is pivotally connectedat its lower end as at 55 to the forward side of the said uppermost slatnear the llower edge of the latter and at its upper end ispivotallyconnected as at 56 to an adjusting yoke 57 cornprising spaced arms 58which straddle the finger wheel 44 and are connected as stated to theupper end of the link 54. The yoke also includes a stem 59 which ispreferably flat upon one side and is disposed with its.

said side resting in contact with the inner surface of a cap plate 60which is secured upon the rear face of the face plate 13 and covers theopening 15. This cap plate is provided with a slot 61 to receive theprojecting peripheral portion of the finger wheel 44, and below thisslot is formed with a vertically extending slot 62 through whichslidably projects a threaded stud 63 carried by the stem 59, a bindingnut 64 being threaded onto this stud and adapted to be tightened againsta washer 65 dis osed between it and the cap plate 60 and t us draw thestem 59 tightly against the said cap plate to secure the yoke 57 inpositions of adjustment. The link`A 154:' is housed between the lfaceplate 13 and the section 6 of the 'top yoke constitutes also a means forpreventing longitudinal play ofthe adjusting 'screw rod 43 and theslides 38 which are connected thereby.-Cfisequently the adjustable endvsections 2 are held more or less rigidly in the positions to which theyare adjusted through rotation of the said finger wheel. It is to benoted that the yoke 57 performs this secondary function without in anyway interfering with adjustment of the yoke to effect adjustment of theslats.l

In that form of the invention shown in Figure 8 of the drawings thestructure is substantially indentical with that previously describedexcept that in this instance a single bar 66 is pivotally connected tooutstanding ears'67 upon the lower fiangesA 68 of the slats 69'. j i

'rdinarily it will be found sufficient to provide a single adjustingmeans such as the slides 38. AadjustinV screw rod 43. and fingerfwheel44, for a justing the end sections of lthe ventilator and this adjustingmeans will preferably be located at the top of the structure. However ifthe ventilator is of exceptional height, it may be `found ,necessary toduplicate this structure at the lower 'portion or bottoni rail oftheventilator so as to provide for an even adjustment of the upper andlower ends of the ends 2. Likewise the structure may be modified invarious other respects if found expedient because of variations in thesizes in which the device will be manufactured.

Having thus described the invention what is claimed as new is:

l. ln a ventilator, a main section, end sections slidably assembledtherewith, and means operable to adjust the said end sectionslongitudinally with relation to the main section, said means comprisinga rotatable threaded adjusting rod, and members connected with the endsections and having threaded engagement with said rod, the said rod andthe said members associated therewith being housed within a part of theymain section and the rod carrying an operating member having a portionextending exteriorly of the said part of the main section.

2. In a ventilator, a main section, end sections telescopically fittingthe ends of the main section andv adjustable to provide for expansionand contraction of the ventilator as a whole, and means operable toadjust the said end sections. the main section including a top railhaving an upstanding portion to rest against the face of the lower railof a. window sash and provided with an overhangingand inturned fiange toprovide a channel, the said end sections having portions slidabljvinterlocking with the said flange. j

3. In a ventilator, a frame including upper and lower rails and endstiles, slats pivotally mounted at their ends upon the said stiles andextending between the same within the 'frame, means connecting the slatsfor movement. in unison upon theirpivots, and means operativelyconnected with one of said slats for singularly adjusting the same aboutits pivots, the said adjusting means comprising a plate memberupon oneof said rails, a

member verticallvadjustable With relation to said plate member, theplate member having a slot extending in the direction ot ad- .justmentof the said member and the inember having a stud projecting through theslot. a nut uthreaded upon the stud for coac- Leaders portions, athreaded adjusting rod extending transversely with relation to thespaced portions of the member, an operating finger wheel upon the saidrod confined between the spaced portions of the said adjustable member,and'operative connection between the oppositelj-Y threaded ends of therod and at the upper edge of said transversely directed portion arrangedreverseljT thereto, slats pivotallv mounted on and extending between thestiles, the lowermost slat having a iange to engage under thefirst-mentioned flange, means for angularlv adjusting the slats. andmeans for adjusting the end sections longitudinally of the -rnainsection.
